Summary: This is not the best radar detector on the market, but among the GPS detectors it is one of the best for the money that you can find on EBAY for less than $120. It will tell you if there is a red light detection and if its on or not, if there is a train or emergency vehicle, ambulance, fire truck, ect. I have one for myself and I got one for my son for Christmas.
Summary: This detector is so much advanced from the older ones, it detects red light cameras and emergency vehicles, just drove to South Carolina and back from Texas and never had a problem. Let me know well in advance of any problem areas and speed traps!
Summary: I bought the Cobra XRS 9550G to replace an older Cobra radar detector. The Cobra had many of the features of other more expensive radar detectors for a reasonable price, and since I never had an issue with the Cobra detector I owned I bought it. The "Speed Trap" and "Camera" feature were easy to set up and you simply update them periodically. To date I have no complaints about the Cobra XRS 9550G.
Summary: once I got the detecter adjusted and programed.I am sure it will be just what I need. I don't live in and area where red light cameras are ,so i'll have to wait till I do some traveling. So far I like the detecter.
